The scarcity of full-frame dslrs is partly a result of the cost of such large sensors. Medium format size sensors, such as those used in the mamiya zd among others, are even larger than full-frame sensors, and capable of even greater resolution, and are correspondingly more expensive. In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the viewfinder, or the image sensor when the shutter release button is pressed. The nikon d3500 was launched back in 2018 as an evolution of nikon's best-selling line of digital cameras. We also rate it as one of the best nikon cameras right now, as well as one of the best cameras for beginners.
